A war of words between Tesco and Sainsbury’s erupted yesterday after the
supermarkets revealed just how hard they had been hit by the squeeze on
their customers’ spending power.

Tesco’s worst sales decline in its home market in 20 years laid bare how
shoppers have struggled under the weight of high petrol prices and soaring
energy bills and left J Sainsbury clear to claim victory in the latest bout
of hostilities between the grocers.
